253 * Older version (pre 3.x?) of the PCRE library do not support
254 * POSIX named character classes (e.g. [[:alnum:]]).
256 * This is a helper function which can be used to convert a regexp
257 * which contains POSIX named character classes to one that doesn't.
259 * All instances of strings like '[:<class>:]' are replaced by the equivalent
260 * enumerated character class.
262 * Implementation Notes:
264 * Currently we use hard-coded values which are valid only for
265 * ISO-8859-1. Also, currently on the classes [:alpha:], [:alnum:],
266 * [:upper:] and [:lower:] are implemented. (The missing classes:
267 * [:blank:], [:cntrl:], [:digit:], [:graph:], [:print:], [:punct:],
268 * [:space:], and [:xdigit:] could easily be added if needed.)
270 * This is a hack. I tried to generate these classes automatically
271 * using ereg(), but discovered that in my PHP, at least, ereg() is
272 * slightly broken w.r.t. POSIX character classes. (It includes
273 * "\xaa" and "\xba" in [:alpha:].)
275 * So for now, this will do. --Jeff <dairiki@dairiki.org> 14 Mar, 2001
